568-155 FEP ENCAPSULATED VITON ORING

Item TEV80155 is a PTFE/Viton Core 90A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-155; 3.987 inch (101.27 mm) ID x 0.103 inch (2.62 mm) CS; 4.193 inch (106.5 mm) OD, with 4 inch nominal ID; 3/32 inch nominal CS for cross-reference against common gland and replacement dimensions. The PTFE encapsulated Viton core compound is selected for the chemical resistance of a PTFE jacket with the elastic recovery of a Viton core. It is with a listed temperature range of -75°F (-59.4°C) to 400°F (204°C), which can help narrow material selection for heat, cold or process exposure. The black color and round profile provide a practical visual identifier during receiving, stocking and installation. This standard industrial O-ring can be used across compatible static and dynamic sealing applications in pumps, valves, cylinders and assemblies. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone.
